I just wanted to know, when you and your partner where told about PGD, did they say they could tell the different between a 'normal' embryo and a 'balanced' embroyo when they were doing the testing? So for example, will they be able to make sure the embroyo won't be passing on the same Balanced Translocation that I have?
Or do they just check that the embryo has the correct amount of chromosomes (ie not UNbalanced)?
Currently, there are mainly two groups of patients for which PGD is being applied:
* In the first group PGD is used to look for a specific disorder in couples with a high risk of transmitting an inherited condition. This can be a monogenic disorder, meaning the condition is due to a single gene only, (autosomal recessive, autosomal dominant or X-linked disorders) or a chromosomal structural aberration (such as a balanced translocation). PGD helps these couples identify embryos carrying a genetic disease or a chromosome abnormality, thus avoiding the difficult choice of abortion. In addition, there are infertile couples who carry an inherited condition and who opt for PGD as it can be easily combined with their IVF treatment.
* The second group consists of couples who undergo IVF treatment and whose embryos are screened for chromosome aneuploidies. The technique is not used to obtaining a specific prenatal diagnosis but rather for screening, properly referred to as preimplantation genetic screening (PGS), to increase the chances of an ongoing pregnancy.
you can can go to the SIRM website, log into discussion boards and post a question and the drs from SIRM will answer it (i recommend posting in the Las Vegas section, the founder of SIRM posts in that one). They also offer FREE ivf consultations over the phone. I've done it 3x!! they are very helpful. I know quite a few of us have posted questions in there about our situations, and gotten reliable helpful solutions.

They told us once it hits the 4 cell state they'll take a cell out and test the DNA of the cell. For us we'd just be testing the 3 and 12 chromosomes, we could test the whole board including finding out the sex of the cells but it's more expensive. They said they'd be able to tell us if it was balanced, unbalanced, or normal. The unbalanced would be destroyed and we'd have the choice about the balanced.
With Coby at birth they are testing his DNA right away to see if he's got normal or balanced. That way we'll know and be able to tell him that he may have fertility problems later in life. But the way medical advances are going hopefully by then it won't be as big of an issues as it is now.
